Answer:
m∠FXM = 24°
Step-by-step explanation:
This problem has a lot of extra data that has no relation to the question. You can basically ignore any business about isosceles triangles and congruent segments.
__
The only thing you need to know is the angle sum theorem:
m∠FXM + m∠MXA = m∠FXA
Filling in the numbers, you get ...
m∠FXM + 72° = 96°
m∠FXM = 96° -72° = 24°
The measure of angle FXM is 24°. (matches choice A)
Answer:
7.5 hours
Step-by-step explanation:
The key here is to find out how much can be done in the same amount ot time
the least common multiple of 5 hrs and 3 hrs is 15hrs
In 15 hours:
- At 5 hours per lawn Norton could mow 15/5 = 3 lawns
- At 3 hours per lawn together thay could mow 15/3 = 5 lawns
In 15 hours Jesse would mow 5 - 3 = 2 lawns
15 hours/ 2 lawns = 7.5 hours per lawn
7.5 hours
--------------------
Here's the math
1 lawn/5hrs + x = 1 lawn / 3hrs
1/5 + x = 1/3
Subtract 1/5 from both sides
x = 1/3 - 1/5
x = 5/15 - 3/15
x = 2/15
x = 2lawns/15 hrs
15hrs/2lawns = 7.5 hrs per lawn
7.5 hours
3) 4r⁻³ · 2r² = 4·2 r⁽⁻³⁺²⁾ = 8 r⁻¹ = 8/r
4) 8k⁵
7) 6xy²
I believe you multiply all sides to get the area and you add all sides to get the perimeter.
